The fixed or variable displacement hydraulic motor-pump (1) includes a motor-pump central rotor (3) in which a hydraulic cylinder (14) is arranged, the rotor (3) being in sealed contact with an input-output spool valve (43) connecting the cylinder (14) with a motor-pump frame (2) while a hydraulic piston (13) moves in the cylinder (14) to push, using a hydraulic piston guided plunger (18), a tangential arm (22) articulated in the central rotor (3), and a tangential arm antifriction roller (28) on a motor-pump peripheral rotor (29) synchronized in rotation with the motor-pump central rotor (3).
